"If the sun is moving away or towards us" it would matter - the angular velocity would be decreasing/increasing, unless the sun is able to both accelerate/deccelerate and steer, which is unlikely to happen ;) |

[[Image:Orbit angular velcoity.png|right|256 px|thumb|Angular velocity while orbiting is much simpler than the general case. The angular velocity is simply the orbiting velocity multiplied by distance. Many situations where one ship is much faster can be approximated to to be like this.]] | [[Image:Orbit angular velcoity.png|right|256 px|thumb|Angular velocity while orbiting is much simpler than the general case.

Instead of measuring an object's speed as m/s or miles/hour, a speed can also be measured as an angle. A good example is the suns movement across the sky, where it moves 360° in 24 hours, which makes the angular velocity 15°/hour | Instead of measuring an object's speed as m/s or miles/hour, a speed can also be measured as an angle.

Just as a circle can be described as an angle of 360°, it can also be described as an angle of 2π radians. Meaning that one radian equals to roughly 57° (360/2π). | Just as a circle can be described as an angle of 360°, it can also be described as an angle of 2π radians.
